"The NATO reaction to the September 11 terrorist attacks on the United States underscores the heightened European recognition of threats to Western security originating from beyond the borders of member nations. Nonetheless the European Allies remain wary of plans to extend missile defenses to their continent. In trying to change attitudes toward missile defense within NATO the administration will need to consider European interests and political and economic realities. The United States should not try to force missile defense on Europe. Nor should this issue be viewed as an exclusively NATO project or a test of Allied fealty. At the same time the Allies need to face the potentially damaging consequences of remaining vulnerable to ballistic missile attack while the United States builds defenses against such a threat. Hammering out a responsible NATO missile defense policy will be far more difficult if the transatlantic debate becomes polarized between those who believe Europe will never agree to missile defenses and those who argue that the continent must be protected regardless of its own wishes."
